Piecing thread tension

I have a number of HST made as leaders and enders. These pieces were often the first sewn after I put in a new bobbin or spool of thread and for some of them the thread tension was not quite right. Do I need to throw these out or can they be used in a scrap quilt if I use them in blocks where the seams are crossed? Is there any harm in using them or are they likely to fall apart when the quilt is used?
Thanks!
